panfion of the oblique mufcles of the abdomen upon 
the mo;t prominent part of the tumor: then I pro- 
ceeded to the making a fecond incifion, of an equal 
length with the former, tranfverfely thro’ the upper 
part of the re£ius mufcle (which had a perfect healthy 
appearance), directing my knife forwards, betwixt 
the cartilaginous portions of the feventh and eighth 
ribs, into the cavity of the thorax ; upon which a 
thick clotted matter, to the quantity of 23 ounces and 
upwards, was difcharged. After the whole of the 
matter was difcharged, I introduced the fore-finger 
of my right-hand into the cavity, with which I evi-

hefion, the mediaftinum, and fuperior part of the 
diaphragm ; which laft had been prefs’d fomewhat 
lower than its natural fituation by the weight of the 
incumbent matter. From whence it undoubtedly 
appear’d, that this great quantity of matter was con- 
tained in the cavity of the thorax. 
After the whole of the matter was difcharged, I 
introduced a linen tent, properly fecured, into the 
cavity ; which was continued to be introduced every 
day for about three weeks, now and then, as occafion 
required, making ufe of the prepared fponge-tent. 
The difcharge of matter was confiderable for the 
firft week, when it began to decreafe gradually, till, at 
the end of three weeks, there was no difcharge at all. 
From this time, fuperficial applications only were 
made ufe of. At the end of five weeks he was per- 
fectly well, and has recovered his former plumpnefs, 
and healthy appearance. 
I muft obferve to you, that, about two years ago, 
he received a violent blow on his left fide by a 
fall ;
